Last year, I joined a brilliant group of researchers for a 3-week deep dive into host–microbe systems. Each week explored a different theme, led by inspiring lecturers. I’m excited to share that videos of their talks — along with presentations by several team members — are now on YouTube:

Theory of host-microbe symbioses: Challenges & opportunities Discussion on mathematical modeling of microbial symbioses with 3 noted areas requiring advancement: nested ecology w/in host or holobiont, holobiont population dynamics & symbiont-mediated speciation www.cell.com/cell-host-mi...

Our article on the challenges and opportunities in studying host-microbe symbioses is now published in Cell Host & Microbe! @cp-cellhostmicrobe.bsky.social www.sciencedirect.com/science/arti...

The team's first preprint is out! Led by ‪ ‪@vishnuprasoodanan.bsky.social‬‬ & @omaistrenko.bsky.social , we asked a question (almost) as old as microbiology: how many prokaryotic species exist on Earth? More specifically, how much diversity is "hiding" in existing metagenomic data? A 🧵.

There are many more stories in the preprint, so go ahead and read it: www.biorxiv.org/content/10.1... We welcome feedback!

For #worldmicrobiomeday, re-sharing our recent Review by @pamferretti.bsky.social, Kelsey Johnson, @sambhawa.bsky.social & @blekhman.bsky.social on the 'Genomics of host–microbiome interactions in humans', which is free to read using this link: rdcu.be/etIRy

🚨 Out now! Chronostrain - a method to profile low abundance strains in longitudinal microbiome samples 🦠💻 @travis.gibsonlab.io @younhk.bsky.social @gibsonlab.io @harvardmed.bsky.social @broadinstitute.org #MicroSky 🦠 #MicrobiomeSky www.nature.com/articles/s41...

We wrote up the process we've developed for processing microbiome data in bulk! Workflow management tools are miraculous for processing a project with lots of samples, but when you have lots of *projects* too, as we do when pulling data from NCBI databases, it gets hard to juggle. #microbiomesky

Excited to share the Compendium Manager -- our new tool for scaling bioinformatics pipelines! Launch thousands of analyses, track progress, and maintain reproducibility. Developed by @richabdill.com. Check it out: arxiv.org/abs/2505.11385

Do people in the same household share strains when they have the same species? How many cells transmit when a strain is shared? Can strain composition be dynamic when species composition is stable? We answer these and related questions for the facial skin microbiome in our latest paper. 🧵[1/10]

Excited to share our latest work on the gut microbiome in inflammatory bowel disease patients. This is the result of hard work across generations of trainees in the Donia Lab, in collaboration with amazing scientists (Nobuhiko Kamada and Lea Ann Chen). www.cell.com/cell-host-mi...

Last week @richabdill.com and @samanthagraham.bsky.social's paper was featured on the cover of Cell! The cover, portraying microbes on shelves shaped like a world map, was possible thanks to the amazing team of illustrators at SciStories ✏️🦠

These are challenging times for science, but I'm happy to share a bright moment: our work is on the cover of Cell today. We built a compendium of human gut microbiomes integrating 168K worldwide samples, revealing patterns of microbiome variation across the globe www.cell.com/cell/current...

Excited to this out in Cell! Check out @samanthagraham.bsky.social's thread for the key findings of this massive effort to uniformly analyze 168k human gut amplicon samples! @richabdill.com @blekhman.bsky.social

Use the Human Microbiome Compendium data! We made the data and code available, & created a website and R package to navigate the compendium. Links: - Website: microbiomap.org - Data: zenodo.org/records/1373... - R package: blekhmanlab.github.io/MicroBioMap/ - Code: github.com/blekhmanlab/...

Today we report a new compendium of human gut microbiomes with >168,000 samples By analyzing this massive dataset, we discovered distinct microbiome patterns across the globe, and show we can predict where a person lives just from their gut bacteria Now out in Cell: www.cell.com/cell/fulltex...

I'm very happy to report that Matt Schechter's PhD work is now online as a pre-print: "Ribosomal protein phylogeography offers quantitative insights into the efficacy of genome-resolved surveys of microbial communities", www.biorxiv.org/content/10.1... Here's a little 🧵 about it.

1/ 🚨 New preprint alert! 🚨 We’re thrilled to share our latest work exploring microbiome & genomic #Bifidobacterium co-evolutionary & functional signatures across diverse animal hosts. This has been a long time coming, & huge credit to Magda for her incredible hard work as first author! 🐾✨👇

Excited to see this out in Cell! If you use microbiome data to look for disease associations, you might want to make sure microbial load is not confounding your results! www.cell.com/cell/fulltex... Congratulations @suguru-nishijima.bsky.social @borklab.bsky.social and others #microsky #microbiome

Two important papers on the gut microbiome and disease —The fecal microbial load is a key determinant confounding prior reports of association with diseases cell.com/cell/fulltex... —Innovative approaches to establish causality and mechanisms science.org/doi/10.1126/...

EMBL's press release: www.embl.org/news/science...

If you have human gut microbiome data (metagenomics or 16S), you can use our tool at microbiome-tools.embl.de/mlp/ to predict cell counts, so that you can find out if any microbiome changes in your study population are actually driven by changes in bacterial cell counts

Hot off the press: "Fecal microbial load is a major determinant of gut microbiome variation and a confounder for disease associations" www.sciencedirect.com/science/arti... See below for @suguru-nishijima.bsky.social 's thread on the preprint! #microsky #microbiome

Excited to share our latest preprint on a novel computational tool to predict fecal microbial load solely from relative species profiles! Our study revealed that fecal microbial load is a substantial confounder in microbiome-disease association studies. www.biorxiv.org/content/10.1...

Intense and very productive week attending #cshlmbiome! I particularly loved the amount of novel results presented at talks and posters, and the very collaborative environment...this should be the norm! 👆 Kudos to the organizers for this fantastic meeting! #microbiome

Our metagenome profiler sylph is now published in Nature Biotechnology! (www.nature.com/articles/s41...)

Mother's milk is often the sole source of nutrition for the baby. Milk also contains diverse bacterial communities -- but how to these bacteria impact the infant gut microbiome? Our latest: www.biorxiv.org/content/10.1...
